Variety-generator approach seeks to reflect the microstructure of data elements in their description for storage and search, and takes advantage of the consistency of statistical characteristics of data elements in homogeneous data bases. (Author)

A system used by five libraries in San Antionio, Tesas, for producing catalog cards, book catalogs, and bibliographies is described. (PF)

A framework for cooperation between Library of Congress and the RTSD/ISAD/RASD Committee on Representation in Machine-Readable Form of Bibliographic Information in regard to changes in the MARC System. (LS)

An access method for bibliographic records that combines features of the search key approach and the inverted file approach. Permits extension of search key technique to large files. (Author/LS)

Gives an overview of MEDLARS II as an example of a major bibliographic processing system that supports on-line access to a number of very large files, has efficient throughput, and is operated on a single large-scale computer. (Author/PF)

Low cost and high capacity microcomputers now have the potential for improvement of library services at various levels. They seem well adapted for text-processing, preparation of local bibliographies and resource guides, and improvement of online database searching. (Author/RAA)

An experiment in manipulating machine-readable library records for use in subject searching indicated that such programs would be useful to extend service outside a single library location. (Author/PF)

Describes a user-interactive system for the selection and display of pictorial information stored on microfiche cards in a computer-controlled viewer. (Author)

The background and functional capabilities of Stanford's library automation system and the hardware environment in which it operates are described. Prospects for extending BALLOTS to network use are summarized. (Author/PF)

Describes operational use of on-line field access, a powerful improvement upon search key access to on-line records and a viable alternative to full key word access; and discusses some of the questions considered at Northwestern University Library during a redesign of the technical services modules of the Northwestern On-Line Intergrated System…

Presents MARC database statistics for use in planning and processing files, selection of subsets, and estimating file growth rates. Statistics are provided on record length, field tag occurrence, data element length per field tag, and distribution of records by Dewey Decimal Division and Library of Congress class code. (Author/RAA)

Reports a computer assisted index emphasizing expanded subject access to the reference collection of the Iowa State University Library. The index displays abbreviated length records and complements existing catalogs. Limitations of subject access and a system for assigning subject descriptors are discussed. (Author/RAA)
